Definitions
- the invention relates to a flat gasket for a piston power or working machine, consisting of at least two laminated sheets of a thickness of 0.05-0.5 mm, which are provided at least on the outward-facing side with a coating made of an elastomeric film has an edge region formed by the outer contour and / or by at least one cylinder bore and / or a water or oil passage of the cylinder head, to which at least one circumferential, first corrugation adjoins one of the sheets and the second sheet bridges the first corrugation.
- Flat gaskets for piston power machines or working machines are known in various embodiments, for example from DE 195 31 232, DE 42 05 824, DE 195 39 245.
- cylinder head gaskets serve to seal the joint between the cylinder head and the cylinder block.
- they usually consist of one or more sheet metal plates connected to form a laminate and have one or more combustion chamber through-openings and one or more liquid through-openings, the latter of which enables the passage of cooling water and / or lubricating oil between the cylinder head and the cylinder block. borrowed.
- a full bead often surrounds the combustion chamber through-openings in an edge area.
- the liquid passage openings are often sealed by a bead which surrounds the opening in an edge region.
- the cylinder head and the engine block are pressed together by the preload force of the cylinder screws.
- the beads of the flat gasket in between are supported against the adjacent sealing surfaces of the cylinder head or engine block.
- the greatest specific surface pressures prevail directly in the edge area of the combustion chamber passage openings and in the area of the cylinder head screws.
- stoppers enclose the combustion chamber passages and act as deformation limiters. In addition to this static pressure, the seal is exposed to dynamic loads during engine operation. The distance between the sealing surfaces is not constant in time and place.
- the object of the invention is to provide a flat gasket with improved sealing action, high elastic resilience, low manufacturing costs and a long service life.
- the combustion chamber passage opening or the liquid passage or the outer contour is delimited in an adjacent edge region by a closed circumferential cavity of the seal which is completely filled with a hydraulic medium.
- the flat gasket between the cylinder head and the cylinder block is pressed by the clamping force of the cylinder head bolts, which creates a constant hydrostatic pressure in the cavity.
- the flexible, tubular edging enclosing the cavity adapts to the inevitable warping during clamping.
- the sealing contact with the sealing surfaces of the cylinder block or the engine block is not lost even when the machine operates the cylinder head and cylinder block as a result of both vertical and horizontal relative movements as a result of the ignition pressure.
- the hydraulic medium enclosed in the cavity causes an equalization of the sealing pressure over the circumference of the opening to be sealed.
- the elastic yielding behavior of the tubular casing improves the sealing effect when the machine is in operation and increases the service life of the false seal.
- This connection can be a circumferential weld connection, for example produced by electron beam welding.
- This ring weld seam connects the sheet metal edge which is bent through 180 ° to the sheet itself and seals the cavity on the outside.
- the sheet metal sheet in the sealing gap facing the combustion chamber is designed to be continuous.
- the all-round bead-shaped thickening forms an enclosure for a combustion chamber and serves as a flame and at the same time as a deformation limiter.
- Suitable hydraulic media are all those materials that help to even out the sealing pressure over the circumference of the opening to be sealed.
- This also includes materials, such as a solder that becomes liquid at operating temperature, or also plastically and / or elastically deformable polymeric materials. It is particularly preferred here if the polymeric material is formed by a thermoplastic, by rubber or by silicone. These materials are chemically inert. The mechanical properties of the sheet enclosing the cavity are not affected by chemical reactions between the hydraulic medium and the metal of the sheet.
- the cavity is enclosed by at least one bead of the sheet and a second sheet bridging the bead, the two sheets being inseparably connected to one another adjacent to the bead.
- two sheets are stacked one on top of the other, one of which has an all-round bead in the edge region of an opening. The other of these sheets bridges this bead.
- the inseparable connection of the two sheets adjacent to the bead prevents a horizontal evasive movement of the bead base seen in the cross-sectional direction when pressed.
- the distance between the legs supporting the bead on the bead base is thus essentially maintained despite the pressing force in the sealing gap.
- the consequence of this is a high elastic resilience of the bead.
- This ensures that the contact between the flat gasket and the sealing surfaces of the engine block or cylinder head, which causes the actual sealing effect, is maintained even with relatively large sealing gap movements
- the cavity is completely filled with a hydraulic fluid and the two sheets are connected in a liquid-tight manner.
- the second sheet has a second bead in the area of the bead, which can be designed differently from the first bead. Due to the differently shaped beads, the flat gasket can be adapted very well with regard to the friction behavior of the different materials of the cylinder head and cylinder block. In cross section, the bead profile can have different shapes, for example U-shaped or triangular.
- the sealing contact area of the flat gasket with the sealing surfaces of the cylinder head and cylinder block can be designed so that even after a long period of operation these sealing surfaces are not damaged by digging.
- the sheets can be made of the same or different materials, for example of spring steel sheet of different thickness. Of course, it is also conceivable that other materials are used, such as plastics instead of the metal sheet.
- the seal can be coated with an elastomeric layer in the sealing area.
- This elastomeric film can be, for example, a rubber layer which is applied to the main sealing surfaces of the metal sheets by spraying or pouring on. Due to the pressing forces in the sealing gap, this rubber layer is pressed in at the roughness depths of the respective sealing surfaces, whereby a micro-seal is achieved.
- a third sheet is arranged between the first sheet and the second sheet and this third sheet is included in the connection between the first and the second sheet, the on both sides of the third sheet metal existing cavities are in hydraulic connection with each other.
- This hydraulic connection can be formed, for example, by a flow opening in the third plate.
- the third sheet has a third bead of a differently shaped profile in the area of the first and second beads.
- the elastic resilience of the flat gasket can be specified within wide limits.
- the hydraulic connection between the cavities prevents the third sheet enclosed between the two outer sheets from bulging.
- the flat gasket can be adapted very well to the different materials of the cylinder head or cylinder block thanks to the beads with different cross-sections.
- a round cross-section or a bead composed of several partial beads increases the specific surface pressures with the adjacent sealing surface.
- the enlarged contact surface with the sealing surface of the cylinder head avoids burying. This is particularly advantageous if the cylinder head consists of a light metal alloy.
- Fig. 1 is a partially sectioned plan view of the invention
- the flat gasket according to the invention is shown in a top view in a partially sectioned illustration in FIG. 1.
- the flat gasket 20 covers the sealing surfaces of an engine block or cylinder head of which cylinder bores
- each of these openings 11, 10 is enclosed in an edge area 9 by a circumferential cavity delimited by a sheet metal.
- the outer contour of the flat seal can also be provided with such a circumferential cavity. The decision is that the cavity is completely hydraulic
- FIG. 2 shows a section of a section through a preferred embodiment of the flat gasket according to the invention.
- the edge of a sheet 1 surrounding a through opening is flanged in such a way that a closed cavity 2 is formed.
- This cavity 2 is completely filled with a hydraulic medium 6. All those substances which bring about an equalization of the sealing surface pressure are suitable as hydraulic medium.
- the hydraulic medium can be a hydraulic fluid, for example.
- a solder is used for the fuel gas seal, which becomes liquid under operating conditions.
- polymeric materials such as thermoplastic, rubber or silicone are also suitable. Different materials can be used for a flat gasket.
- the flanged edge of the sheet metal is connected to the sheet itself by an inseparable connection 14. This connection 14 can be made liquid-tight and at low cost, for example by electron beam welding.
- the sealing area of the seal is coated with an elastomer layer 13.
- Figure 3 shows a particularly preferred embodiment as a section of a section of the flat gasket.
- the cavity 2 is formed by the bead 3 of a sheet 1, which is covered by a second sheet 4.
- Both sheets 1, 4 are inseparably connected on both sides of the bead 3 by a connection 14.
- the sheets can be 0.05 mm to 0.5 mm thick.
- both sheets 1, 4 are coated with an elastomeric layer 13.
- the sheet 4 can be flat or, as shown in FIG. 4, have a bead opposite the bead 3.
- the resilience of the flat gasket can be optimally adjusted.
- the sectional drawings in FIG. 5 and in FIG. 6 each show a very particularly preferred embodiment of the invention.
- a third sheet 8 is arranged between the two sheets 1 and 4.
- connection 14 connects the three sheets 1, 8, 4 on both sides of each bead in a material-locking manner.
- two cavities 2, 2 ' are formed, each of which is filled with a hydraulic medium.
- a through opening 16 in the sheet 8 lying therebetween forms a hydraulic connection between the cavities 2, 2 ′ adjacent to sheet 8.
- the sheet 8 can also have a bead 15 in the region of the adjacent cavities 2, 2 ', which increases the elastic resilience of the flat gasket. Due to different cross-sectional shapes of the beads 5 and 3, the flat gasket can be adapted very well with regard to a different friction behavior of the respective materials of the cylinder head or cylinder block.
- the contact area of the flat seal with the flat sealing surfaces of these machine parts can be designed in such a way that the sealing surfaces are not damaged even after a comparatively long operating time.
- a preferred embodiment of the invention is shown in FIG. 7.
- the cavity 2 delimiting the passage opening is formed by the edge of the sheet 1 that is flanged back on itself.
- the bent back edge is not welded, but is pressed between two beads of the active layers 17 and 18 by the prestressing of the cylinder head screws.
- An intermediate layer 19 is arranged between the layers 17 and 18 adjacent to the flanged back edge.
- the hydraulic medium 6 enclosed in the cavity can be a plastically deformable polymeric material, for example a thermoplastic, rubber or silicone.
- layers 17 and 18 sandwich cavity 2.
- the flat gasket can also be constructed such that only one of the active layers 17 or 18 is present.
- the flat gasket according to the invention can also comprise cover layers on the outside.
